4 Claims. (01. 257159) Our invention relates to new and useful imanipple or bushing member 11, preferably of cast provements in radiators,and more particularly iron, which extends substantially across the to aninlet nipple or bushing embodied in the ra width of the first or inletcolumn or section. The diator. member 11 is preferably in the form of ahollow In the heating of radiators by steam, it' freplug having asubstantially cylindrical body p01'- 60 quently occurs that the water ofcondensation tion 12 and a substantially cylindrical internal whichcollects at the bottom of the radiator will chamber or bore 13, which isclosed at its inner cause water hammer when steam is admitted end by awall 14 normal to the axis of the bore, to the cold or cool radiator,and the water hamand which at its other or outer end has an interv meris more pronounced and certain of occurring nally threaded inlet port 15to receive a steam G5 in a radiator having the steam inlet at anupsupply pipe or conduit member. The portion 12 per end nipple openingand a trap controlled outis externally screw threaded, as at 16, for apart let at the opposite lower end. It is also common of its lengthadjacent its outer end for threaded for the radiator heated by steam totrap air, i. e., engagement with internal threads in aperture 6.

member 11, in accordance with our invention; the volume of steamdirected internally across the top of the radiator is greatly reducedby. the aperture 19 and the greater portion of the steam admitted to theplug member passes through apertures 18 radially into the inlet sectionor column. As a result, most of the steam admitted to the bushing passesdownward in the first or inlet column and then horizontally throughtheas the steam passes through each of the bottom openings, a quantity ofthe steam will split off andrise in each column, as indicated by thearrows y, it being apparent that the upflowing lquantities will taperoff from the inlet column toward the outlet column. It will thus be seenthat the air pocket under line AA is eliminated, the steam which risesin the respective intermediate columns carrying the air upward :beforeit into the path of the jet M, which serves ftoIsweep the air into anddown the end outlet column, so that the air in the radiator is driven,outiahead of the steam and before the steam reaches the trap 21.Elimination of water hammer, is also accomplished, because, as will beseen, the greater part of the admitted steam is moving through thebottom nipple openings 3 toward the outlet 8, and therefore acts todrive thewater ahead and into line 22 through the ;;open trap. Due tothe elimination of the con- -densate and the air, the radiator will heatuniw-formly' throughout its area, so that the bushing member 11 causesan equalization in the heating gup'of the columns. p
